Hello, I am in the process of beginning a 289 build for my 66. I stumbled across an add on Craigslist for a 289 block out of a 67, with 55,000 orginial miles. She says that there was a rebuild done, and the compression is great. Anyway, I guess that it is in great shape with only minor surface rusting. It is listed for 175, I guess my question is why is it so cheap? I am pretty new to classics but I figured something that runs and with that low of mileage would go for a lot more. What do you guys think? Thanks so much in advanced and have a nice day.
